Problem: I see the error message ‘Custom program error: 0x1’ while trying to do a transaction on Solana.
Cause: There isn’t enough SOL in your Solana account’s available balance to pay a transaction fee (or, after a fee is deducted, your account’s SOL balance would fall below the minimum ‘rent’ requirement; 0.0008 SOL for standard accounts, 0.0028 SOL for stake accounts/token accounts).
Solution: Add some SOL to your account and try again.
